Abstract

L'invention concerne un système et un procédé assurant la synchronisation de données pour des dispositifs distants. L'architecture de ce système comprend un dispositif distant contenant des données de dispositif, un dispositif serveur contenant des données originales et des données de mise à jour des données originales, ainsi que des données delta qui n'identifient que les modifications entre les données originales et les données de mise à jour. L'invention peut également servir de procédé de transmission de données modifiées sur un serveur à un dispositif distant. Ce procédé consiste à : (1) fournir des données originales; (2) créer des données mises à jour à partir des données originales; (3) produire des données delta qui n'identifient que les changements entre les données originales et les données mises à jour; et enfin, (4) transmettre les données delta à un dispositif distant.
